' milxicomisnsmemes To aZZ whom it may concerm v V Be it known that I,SonnN Hews citizen of the United States, residing at Spokane, in thecounty of Spokane and State of Viashingtcn, have invented a new anduseful Milk-Condenser, of which thetoilewing is a specification.

The present invention relates to mill; condensers, and is particularlyan improvement over the milk condenser disclosed in my former Patent No.1,042,912 issued @ctober 29, 1912. v The present invention contemplatesthe production of a milk condenser of the general character of theapparatus disclosed in the above mentioned patent but which shallbenzene simple, compact and inexpensive in construction, as well as ofhigher eficiency, and sel'viceaiiility.

The present invention incorporates the prominent features oftheapparatus disclosed intlie aforesaid. patent, and in addition theretoincorporates certain additional arlvantages, the cardinal of which isthe provision whereby the apparatus may be connected to a. tank or othersuitable supply of milk and inortier that the milk may be automaticallysupplied to the apparatus as the milk within the apparatus condensestine to the desiccating action.

A further feature, as provided by the present improved apparatus, is theprovision of a turbine rotor adapted to be ectuetetl by the steam forheating the milk, in order that "the improvetl'apparatus.

Thus,steam or any other, heated "fluid may be stimittetl into the jacket soas to actuate the rot-or and then ascend within the jacket to surroundthe milk re condenses within the jacket.

The shaft 16 passes through the bottom of the milk receptacle, thebottom being pro vided with an upstanding packing receiving collar 22011 which is screw-threaded a gland 3. 4-. horizontally rotatingagitator 24 is secured to the shaft within the milk receptacle, while adisk or sprayer 25 is secured to the shaft within the casingS or abovethe milk. receptacle.

A fan 26 of any suitable character is secured to the shaft above thepartition 13 or,

within the chamber provided by the partition, said fan being rotated bythe shaft so as to create an upward current of air through the opening 11' in the partition and outwardly through the exhaust conduit 15. Thus,the rotary fan or centrifugal blower will tend to rarefy the air withinthe casing 8 and above the milk receptacle, thereby causing air to bedrawn in ings 11 and 11, which will be drawn upwardly through the casing8 and around the sprayer or breaker 25 to the rotary fan.

An upstandin 1 reduction pipe 27 is secured to the flange 9 adjoiningthe wall of the milk receptacle and has its upper end bent. to form anangular arm 28 overhanging the sprayer 25. The'eduction pipe 527 ispreferably arranged adjacent the inlet 11', although its particularlocality does not alter its environments.

1 'The milk supply pipe is denoted by the numeral 29,

the same entering the casing 8 adjacent its with an outlet spout 30adjacent its lower end and passing through the jacket l and having adischarge or outlet faucet 31.

The apparatus as above described and as illustrated in the drawing willtherefore possess the advantages and features pointed out in theintroduction, and so combines and revises the apparatus disclosed in theaforesaid patent to increase the efiiciency and utility of theapparatus.

in operation, the supply or feed pipe 29 is connected to a suitable tankor other receptacle containing on milk to be condensed the flow of milkbeing regulated or gown-nod by means of any suitable valve, as usual.After the flow of milk has been established,

in order to properly till the milk receptacle,

through the open:

by means of the flange 9. The air in the milk as it-is'undergoingdensed,- or the water'will against the walls of the .casein and otherpeptothe steam line may be opened sons 50 admit;

()r, if desired, the shaft ma be driven by any other suitablepower, it not being ne essary to employ the'rotor, the me running freewith the shaft when the latter is driven by abelt or otherwise, and thesteam .merely being aclmitted for heating the mil le-reeeptaclo. lVhenthe agitater 2 t is'rotated Wll'll the shaft, the milk within thereceptacle will be whirled to form an eddy or a wall of milk'aroundthesidcs of the milk receptacle, this centrifugal action forcing themilk upwardly under the flange 9. The superincumbent milk will thereforechoke or cut off the passage through the supply pipe 29, and the flow offresh milk into the apparatus'will be re- .tarded or arrested, until thedesicc ating acthe quantity of the milk and tion reduces thereby admitssullicient fresh milk to make up for the loss. The upward thrust of themilkagainsi. the flange 9 also forces the milk up'thc eduction pipe 27so as to be discharged on the sprayer 25, the milk being broken andthrown from the spraye'i 'thereby to form a foggy ---or mist like cloudin the casing 8. The steam or water vapor given oil" by the milk willtherefore be drawn ofi by the centrifugal fan and will be dischal edthrough the exhaust; conduit 15, the tmrdor heavier constituentsdescending and being directed back into the milk receptacle being drawnthrough the casing 8 will also the evaporating or dcsiccating action.Thus, as the operation progresses, the milk .will be conbe ev poratedand drawn oil;- and the quantity of milk within the apparatus beingreduced by the desiccating action, will permit fresh milk to flowgradually into the milk receptacle through the feed pipe 29. The milkbeing thrown" milk rece tacle by the centrifugal action caused by t erotary agitator 24 posure of the walls of-the milk. receptacle so. thatthe incrustat-ion or scorching of the milk is eliminated or eradicated.After the aerate will thus prevent the interior ex I operation ordesiccating action has ensued for the proper time so as to sufficientlyreduce the milk, which in practice is one third,- the rotation of theshaft is stopped, and the condensedmilk may be drawn of through thefaucet 31. The milk, thus condensed, will be of undiminished solubilityand the proteids will retain their original peptogenic properties.

From the foregoing, taken in connection with the drawing, the advantagesand capa-, bilities of the present apparatus will be apparenhit beingnoted that this apparatus ncezese may be employed for condensing ordesiccating various other liquids.
